IMPROVEMENT IN STOVE-LEG FASTENINGS.

Specification forming part of Letters Patent No. 196,705, dated October30, 1877; application filed March 15, 1877.

To all whom it may concern Be it known that I, THEODOREH. ROBERTS, ofDetroit, in the county of Wayne and State of Michigan, have invented anImprovement in Stove-Leg Fastenings, of which the following is aspecification:

The object I have in view is to combine with a stove-leg a device thatwill automatically lock the shank-plate to the dovetail lugs under thebase-plate when inserted in the same;

and it consists in a weighted dog pivoted to a lug east on the underside of the shank-plate of a stove-leg, as more fully hereinafter setforth.

Figure 1 is a perspective View, showing a leg locked to one corner ofthe base-plate of a stove. Fig. 2 is a longitudinal section through theshank-plate and locking device at w a.

In the drawing, A represents a portion of the base-plate of a stove,cast with pendent dovetail lugs a a, for the insertion of the shankplateB of the stove-leg. The latter has cast on its under side a lug, b, atthe inner end, to which is pivoted, by a wire rod, 0, alever-dog,

O, which is forked to embrace said lug. The extended inner end of thedog is weighted, so as to drop and throw up the shorter arm,

which is laterally extended, terminating at each corner in a roundedstop, d, in the path of thelugs a. When the shank-plate is inserted thepoints or stops d (1, coming against the outer ends of the lugs a a, aredepressed and pass under them, while the shank-plate is being inserted,until they are behind them, when the heavy end of the dog drops andthrows up the stops (1 d behind the lugs to a, which thus locks the legto the stove. To withdraw the leg, the heavy end of the dog must be elevated and sustained while withdrawing the shank-plate.

What I claim as my invention is The lever-dog O, pivoted to a lug underthe shank-plate B of a stove-leg, substantially as and for the purposeset forth.
